This paper aims to determine the correlation of the throw distance of cyclist and electric bicycle in traffic accidents with throw vehicle impact speed. A total of 22 vehicle-electric bicycle accidents were sampled from IVAC database, China. The selected accidents were reconstructed by using PC-Crash and Madymo programs. The relationship between throw distance and vehicle impact velocity was analyzed by using logistic regression model The relationship curves were obtained based on the calculated parameters. With increasing of the vehicle impact velocity, an increase of throw distance was observed. When the vehicle impact velocity was above 30km/h, the throw distance of electric bicycle was larger than that of cyclist. By comparing of results from the PC-Crash and MADYMO simulations with observations from in-depth accident investigation, the feasibility of the reconstruction method and the validity of the numerical model were evaluated. This research could provide a basis for further study on the dynamic response and injury prevention of cyclist.
